Endovascular Treatment of a Forty-Year-Old Post-Traumatic Knee Arteriovenous Fistula.

ABSTRACT

Arteriovenous fistulas (AVFs) of the lower extremity are uncommon. The main causes are traumatic or iatrogenic, with 15% of traumatic AVFs occurring in the popliteal vessels. Herein, we present a 60-year-old female with a traumatic AVF caused after a car accident 40 years ago. The patient presented with right leg venous claudication and symptoms of congestive heart failure. Duplex ultrasound of lower limb vessels revealed an AVF at the distal part of the tibiofibular trunk. The patient was successfully managed with an endovascular approach using a coil-assisted covered endovascular repair technique of the tibiofibular bifurcation (CERTIFIB) with excellent results and distal vessels patency. At 3 months follow-up, patient presented with an impressive regression of 3 cm of the lower extremity oedema and improvement of both claudication and heart failure.
